Gasification Users Association EPRI’s GUA is an organization of users and potential users of gasification technology. Its purpose is to create a networking organization to exchange information of a non-confidential nature on the practice and operation of gasification and its associated technologies. Membership in the GUA is not included in PS66B (or all P66) membership Meets twice a year Once in US after Gasification Technologies Conference Once overseas in conjunction with a gasification-related technical conference

Other Supplemental Projects Detailed technical support for advanced coal power project development EPRI is seeking development partners for the liquid CO 2 coal slurry concept and laser-based syngas composition and temperature sensor that have been nurtured with Technology Innovation funds to date Outside sponsors needed for next step in development of these technologies

What do you want to see as R&D? EPRI wants to make sure you are getting what you need as a funder of our work What would you like to see in CoalFleet? How can we support you as a participant in CoalFleet?
